Surviving the Aftermath

This requires 30 energy producing buildings such as Solar and Wind. From my experience this is 30 in the colony at the same time requiring alot of Parts, Concrete, Metal and component's. A Solar Panel requires the least amount out of all 4 with 25 metal and 6 components each. 750 metal and 180 components all in however as you play the game having wind makes the most sense for long term playing.
